查了一天，两个重要点 1.我放弃了友盟的分享和友盟内部的微信登录 2.在appDelegate里写这两句，控制待依然会打印，忽略这个错误，你应该也能正常收到onResp的代理回调  func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {        return WXApi.handleOpenUniversalLink(userActivity, delegate: self) }     func onResp(_ resp: BaseResp) {           if let resp = resp as? SendAuthResp {         } }
